In 1984, under the guidance of Archbishop Iakovos, The Archbishop Iakovos Leadership 100 Fund was created as an endowment fund of the Greek Orthodox Archdiocese to provide an opportunity for Greek Orthodox leaders to support the life-sustaining ministries of the Church.

In 1998, The Archbishop Iakovos Leadership 100 Fund Incorporatedwas formed as a 501(c)(3) New York corporation that supports the National Ministries of the Greek Orthodox Archdiocese in advancement of Orthodoxy and Hellenism.

Leadership 100 members pledge $100,000, which is paid over a period of 10 years or less, except for young professional and junior members who pay the pledge on a graduated scale.

Since its inception in 1984, Leadership 100 has distributed more than $48 million in grants that have ranged from providing scholarship funds for individuals studying for the priesthood at Hellenic College/Holy Cross School of Theology to supporting a variety of National Ministries. These have included Religious and Greek Education, Youth, Young Adult and Camping Ministries, Family and Marriage Services, Inter-Orthodox, Ecumenical and Interfaith Relations, Internet Ministries and Home Mission. Leadership 100 has also provided humanitarian assistance during national and international crises.

The Leadership 100 Executive Committee approves grants submitted by the Grant Committee after consultation with the Archbishop. The principal of the Fundremains permanently restricted and inviolate.

Today, with more than 1,000 members, Leadership 100 is a philanthropic driving force within the Church, the Greek American Community, and in the nation and the world that transforms institutions and lives.
